Presentation of Willebroek

The municipality of Willebroek (23,300 inhabitants on 1 January 2007;
2,741 ha) is located in the region of Klein Brabant, 15 km north-west
of Mechelen. The municipality of Willebroek is made since 1976 of the former municipalities of Willebroek, Blaasveld, Heindonk and Tisselt.

The Willebroek Canal (28 km), linking Brussels to the river Rupel (and
therefore to Antwerp via the Scheldt), was authorized by Mary of Burgundy in 1547. The building of the canal started in 1551 and was completed ten years later.
The canal replaced the Zenne, deemed too sandy, as the mean waterway
between Brussels and Antwerp, to the great wrath of the inhabitants of
Mechelen. Once the holders on a profitable toll on the Zenne, they
attempted to postpone the building of the new canal, which had already
been allowed by Philip the Good in 1436.
In Brussels, the Willebroek Canal was connected to the
Brussels-Charleroi Canal in 1832. The canal was completely revamped in 1922 and 1955. Originally joining the Rupel near the village of Klein-Willebroek, the canal was extended 4 km to the north-west, up to the lock of Wintham.

"On the Willebroek Canal" is the second chapter of "An Inland Voyage" by R.L. Stevenson (1919), including:
"Next morning, when we set forth on the Willebroek Canal, the rain began heavy and chill, The water of the canal stood at about the
drinking temperature of tea; and under this cold aspersion, the surface
was covered with steam.[...]"
